To all whom it may concern.

Be it known that I, HAROLD D. Cannon, a citizen of the United States, and resident of Fairfield, county of Fairficld, State of Connecticut, have invented certain new and useful Improvements in Hydrocarbon Motors,.of which the following is a specification.

This invention relates to hydrocarbon motors and more particularly to temperature regulating means for oil pumps employed in connection with said motors.

One object of the invention is to provide means for maintaining an equitable temperature of the body of the oil pump, to thereby facilitate the flow of oil in cold weather upon starting.

Another object of the invention is to enable the utilization of the thermostatically controlled by-pass now employed in connection with the radiator and water pump, in accomplishing these ends.

With the above objects and others in view, theinvention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated in the accompanying drawings, in which J Fig. 1 is a side view in elevation, in vertical section, and l Fig. 2 is an end elevation of a motor similar to that shown in Fig. 1, the section at the upper part thereof being substantially on the line 2-2 of Fig. 1.

Referring to the drawings, 10 indicates a hydrocarbon motor of any desired ty e, and 11 a water jacket surrounding the cy inders thereof.

Leading from the upper part of the water jacket of the motor is a pipe 12 which communicates with a chamber 13 in which is adapted to be mounted a thermostat and valves controlled thereby. From the chamber 13 a pipe 14 leads to the upper part of a radiator 15. From the lower part of the radiator a pipe 16 leads to the suction end of a water pump 17. The delivery end of this water pump communicates with a pipe 39 leading to the lower part of the water jacket 11 of the motor, through a mani-' told 18.

' Referring to the control device, a valve 31 connected to the stem of a thermostat 23 is held by the contracted condition of the thermostat against a seat 24 at the junction partly engine between the pipe 12 and pipe 14, the latter leading to the radiator, so that communication between the motor water jacket and the radiator is cut 0d. At the same time, a valve 32 also carried by the stem of the thermostat is held away from a seat 26 at the junction 26'.

The valve 32 controls the passageway of a pipe 33, leading through the water jacket 3% of an oil pump 35, from the opposite end of which. water jacket a pipe 36 leads to the suction end of the water pump 17. 'lhis water jacket of the oil pump is adapted to have communication with the water circulation system for the purpose of warming the oil pump upon starting the engine.

In the arrangement described, whenthe is first started, the communication from the water jacket of the motor to the by-pass and thence to the water jacketiof the oil pump will be open and as the engine warms up the water will be warm and will in turn impart its heat to the oil pump, thus facilitating the flow of oil. When the heating of water becomes excessive the thermo= stat will be expanded thus closing the valve 32 controlling the by-pass and cutting ed the flow of water throu h the water jacket of the oil pump. The oifpump water jacket is thereafter closed from communication with the water circulation system until the engine ceases to operate and cools ofi.

Having thus described my invention, what I claim and desire to secure by Letters Patout is: I

1. In a combination with a water-jacketed hydrocarbon motor, a water-jacketed oil. pump, a water pump, a radiator, a by-pass eadmg from the motor jacket around the radiator and including the oil pump jacket, a thermostat, and a valve controlled thereb for closing or opening the byass, and either passing the water through t e radiator or through the by-pass and oilpump jacket. I

2. In combination with a water-jacketed hydrocarbon motor, a water-jacketed oil pump, a radiator, a by-pass leading from the water jacket of the motor to the oil motor water jacket and said oil pump jacket, and the other valve controlling the communication between said motor water jacket and said radiator.

3. In combination with a water-jacketed hydrocarbon motor, a water-jacketed oil pump, a radiator, a by-pass leading from the Water jacket of the motor to the oil pump jacket, a conduit connecting said motor water jacket and said radiator, a thermostat having connected thereto a air of valves, one of said valves controlling the communication between said motor water jacket and said oil pump jacket, and the other valve controlling the communication between said motor water jacket and said radiator, said valves being so constructed and arranged that the by-pass control valve will close as the radiator control valve is opened.

4. In combination with a water-jacketed hydrocarbon motor, a water-jacketed .oil pump, a radiator, a by-pass leading from the water jacket of the motor to the oil pump jacket, a conduit connecting said motor water jacket and said radiator, a thermostat having connected thereto a pair of valves, one of said valves controlling the communication between said motor water jacket and said oil pump jacket, and the other valve controlling the communication between said motor water jacket and said radiator, said valves being so constructed and arranged that the radiator control valve will establish communication between the motor water jacket and the radiator before the by-pass control valve interrupts communicatlon between the motor water jacket andthe oil pump jacket.

5. In combination with a water-jacketed hydrocarbon motor, a water-jacketed oil pump, a radiator, a by-pass leading from the water jacket of the motor to the oil pump jacket, a conduit connecting said mot'or water jacket and said radiator, a ther-.

mostat having connected thereto a pair of oppositely opening valves, one of said valves controlling the communication between said motor water jacket and said oil pump jacket, and the other Valve controlling communication between said motor water jacket and-said radiator.

In testimony whereofl afiix in Si ature.
